Dunkley, Thomas- Bishopgate, Middx 1814

I have researched my Dunkleys back to GGG Grandfather Thomas, a silk dyer living in Bishopgate, London, Middlesex in 1814 at the time of his son James' birth.James, also a silk dyer "emigrated" to Macclesfield where my dynasty can be documented and verified. Any info on my Thomas would be extremely helpful.
